4 Installing the Air Locker

c Refer to your vehicle service manual for the specified maximum

and minimum amounts of backlash. If the backlash is not within the

specifications then the differential will have to be removed and re-

shimmed.

4.8.1 Re-Shimming the Backlash

NOTE : This step is only necessary when adjusting for

incorrect backlash.

c Reapply the spreader to the differential housing.

c Remove the bearing caps.

c Remove the differential.

c To increase the amount of backlash, reduce the shim thickness ‘D’

(Fig.5.) and increase the shim thickness ‘E’ (Fig.6.) by the same

amount. Reverse this step to decrease the backlash.

c Remount the differential as before.

c Release spreader tension.

c Check backlash again as before.

4.9 Profiling the Seal Housing Tube

c Without using sharp, jagged tools such as pliers (usually your

hands are the best tool for this job), bend the seal housing tube so

that it closely follows the profile of the differential housing and

protrudes through the bulkhead port in the differential housing (refer

to Fig.11., 12., & 13.).

c Trim the tube to length using automotive brake line cutters.

Figure 11.
